I haven't had a relaxer in 2 years!
But when I was relaxing Optimum dried out my hair, Elasta QP reverted easily, ORS was good, Silk Elements was better but Phyto was the best! The overall health of my hair changed drastically with its use. Only drawback was there was something different about purchasing online (Polly & Co.) and purchasing in store (Sephora). The online product was smoother than that from the store.
